    Polymer drag reduction of a zero-pressure-gradient boundary layer (1991)

    Notes: The wall shear stress of a zero-pressure-gradient boundary layer was reduced by slot injection of a 1000 ppm solution of Separan AP-273 at 5.1 times the flow rate in the linear sublayer. Velocity and concentration data were acquired at four streamwise locations that correspond to a Reθ range of 2478–3935 in the Newtonian boundary layer. The slope of the logarithmic region of the mean velocity profile in the drag-reduced flow increased over the Newtonian slope. The sum of the viscous and Reynolds shear stresses was less than the total shear stress for 6(approximately-less-than)y+(approximately-less-than)100.

    Notes: Abstract Velocity techniques for detecting ejections have been systematically examined by separating the detection schemes into trigger and delimiter algorithms. A new technique for grouping ejections based on a period of quiescence between bursts was also developed. The combination of improved ejection detection and the new grouping technique have reduced the error in the time between bursts from 25% to 10%. There is a similar improvement in the uncertainty.
